New type of G-Mond-weir type primal-dual model and their duality results with generalized assumptions

Ramu Dubey, Vishnu Narayan Mishra

In this paper, a generalization of convexity, namely G f-invexity is considered. We formulate a Mond-Weir type symmetric dual for a class of nondifferentiable multiobjective fractional programming problem over cones. Next, we prove appropriate duality results using G f-invexity assumptions
